Natasha Richardson

Natasha Richardson portrayed Patty Hearst in the film of the same name.

Natasha stads with Alan Cumming. Richardson, who was being treated at a Montreal hospital, is being transported to New York this afternoon so her mom Vanessa Redgrave, two children and other loved ones can say goodbye before she’s taken off life-support, friends said.

But an hour later, she complained of an extreme headache and was rushed to a nearby hospital. Liam Neeson, husband of the Broadway and screen star, left shooting of his movie in Toronto to rush to Richardson’s side in Montreal and now on the trip home.

Richardson was on a beginner’s slope and reportedly not wearing a helmet when she fell – although headgear is not required.

“She did not show any visible sign of injury but the ski patrol followed strict procedures and brought her back to the bottom of the slope and insisted she should see a doctor,” said a statement from the resort, which is almost 80 miles northwest of Montreal.”Approximately an hour after the incident Mrs. Richardson was not feeling good.”

Richardson was initially taken to the Centre Hospitalier Laurentien in Sainte Agathe and was later transferred to Hopital du Sacre-Coeur in Montreal.

The actress – who is the elder daughter of Oscar-winner Vanessa Redgrave and late director Tony Richardson – comes from a long line of noted British players.
